hi all, im new to this site and just ordered my first uno and midi sheild, but while waiting for them to arrive in post, loads of idea's have come to mind, so please bare with me. heres my question - is it possable to have an lcd screen, with all the important data available on a scrolling mechanism, and also the lcd linked to and interactive with a potentiameter dial or up and down buttons (ie inc and dec).

the idea i have is with midi, and to send midi control mesages, program changes and all things midi, be able to see a visual interpritation of midi data and then send that data out to my musical equipment. the lcd would be used for, a visual display (scrolling system) for midi implimentation information, connected to a dial or inc and dec buttons to send midi data to my gear.

OP, depending on the midi shield (please provide link), my phi-2 shield may be able to stack on top of it. It has lcd and buttons and I have released lots of libraries and codes to support this shield. I have also developed an LCD keypad panel with serial interface so you only need 2 I/O pins to control the display and all 16 buttons and buzzer etc. Take a look at this one link if you want some details:

It makes programming buttons as easy as serial.read, which is like the second example you go through when you get your arduino.
